Add full CRUD + UI for all card sub-resources (tags/labels, assignees, checklists
with items, comments with markdown, file attachments). Restructure CardModal into
a two-column layout with lazy-loaded data. Upgrade card thumbnails with named label
pills, urgency-colored due date badges, checklist progress indicators, and SVG icons.
Add board categories with filtering on the listing page. Include markdown rendering
with DOMPurify sanitization and .prose CSS styles.
